Need help finding a nursing home?

Recently, my mother had to look at nursing homes for her father. It took awhile to find someplace that had the proper care for the elderly but wasn't extremely expensive. Luckily, my mother is a nurse so she knows exactly what to look for. I don't know that I would have known what questions I should have asked or what would constitute "proper" care. Both my mother and my grandmother worked in nursing homes when I was younger but that wouldn't make me an expert on the subject. I really would need someplace like where I can get tips from experts and talk to people who have had to look at homes before. If I'm lucky, my mother will stay healthy for a very long time so I won't have to try to find someone else to take care of her. While she's still too young for it now, the years seem to pass so quickly and I'm dreading the day that she will be "old."
